This article reviews the evidence and theory pertaining to a form of perspective-taking failure—a difficulty in setting aside the privileged information that one knows to be unavailable to another party. The authors argue that this bias (epistemic egocentrism, or EE) is a general feature of human cognition and has been tapped by 2 independent and largely uncommunicating research traditions: the theory-of-mind tradition in developmental psychology and, with more sensitive probes, the “heuristics and biases” tradition in the psychology of human judgment. This article sets the stage for facilitating communication between these traditions as well as for the recognition of EE’s breadth and potential interdisciplinary significance: The authors propose a life-span account and a tentative taxonomy of EE; and they highlight the interdisciplinary significance of EE by discussing its implications for normative ethics.
